Colour Confusion

Colour Blindness, ColorView and Chromagen

Here at VisionCare Optometry we provide a full colour vision testing service to people who are colour confused/ colour blind. You may also find our section on Vision and Colour of interest.

Genetic red/ green colour blindness or colour confusion is caused by a difference in the genes carried between generations and can be be traced by the father – daughter – grandson route. For the female to be colour blind, she needs both parents to be colour confused or for the father to be colour confused and the mother to be carrying the necessary genetic modification.

At VisionCare Optometry we test for colour confusion using both computers with calibrated screens and a number of manual tests including the standard Ishihara, City and Waggoner tests.

Treatment for the condition can be via one of two types of lenses:

  • The Chromagen lens works by the haploscopic effect, where a single colour lens (with a tinted centre) is worn over the non-dominant eye.
  • The ColorView lens works by removing the wavelengths of light which are causing the colour confusion.
  • We have had great success with both lenses and recommend that if you are are colour confused, you come along for a test.

Please call us to arrange an appointment or you can contact us via email.

More About Color View Lenses

ColorView lenses are a multi-coated lens developed from an original patent by a Japanese company. They work by removing those wavelengths of light that are causing the colour confusion and from our experience we can ‘treat’ approximately 80% of the patients we see in practice.

More About Chromagen Lenses

The Chromagen lens was developed in early 1990’s and works via the haploscopic effect, whereby, in the majority of cases a single coloured lens is placed in front of the non-dominant eye. The resulting colour disparity between the two eyes results in enhanced colour perception.

Overlays and Precision Tinted Lenses

At VisionCare we are able to prescribe both overlays and precision tinted lenses following statistical based computerised screening and by use of the Intuitive Colorimeter.  Visit our section on Vision Assessments for more information about the Meares-Irlen Syndrome.
